My lower lip has peeled on occasions but hasn't for ages. It usually used to peel after holidays abroad when I'd usually be drinking alcohol for extended periods.
Whether it's the Batrafen or the Dovonex which prevents this happening I honestly don't know but the combination of the two still makes my lips more manageable although they still occasionally have bad days.
And the fact that your white dots are in areas where your lips have healed doesn't blow any of my theories out of anything. The lad who started this thread has white dots and his EC has responded to anti- Acne type cream.
I know I didn't have white dots before EC and I know that the worst affected area (The line across the top lip where inside of the mouth meets outside) is the area where these dots are concentrated. In my case I'm almost sure there's a link...
